These moist chocolate chip cupcakes always deliver a rich flavor thanks to a duo of sugars, fragrant vanilla, mini chocolate chips in every bite, and a swirl of chocolate buttercream. When I want a classic crowd-pleasing dessert, this recipe never lets me down—kids and adults eat every crumb.
I fell in love with these during a family birthday weekend because they vanished even before dinner was served. The balance of tangy sour cream and deep chocolate buttercream is just irresistible.
Ingredients
- Unsalted butter: makes the cupcakes tender and gives a rich buttery flavor. Use butter that dents but holds its shape for easiest mixing.
- White granulated sugar and light brown sugar: both sweeten and add moisture. Brown sugar brings slight caramel notes. Always pack the brown sugar for accurate measuring.
- Large eggs: at room temperature create a fluffy crumb. If you are in a rush, submerge eggs in warm water for a few minutes.
- Cake flour: provides a soft texture. Look for a finely ground one and measure by spooning and leveling for lightness.
- Cinnamon: gives subtle spice. Use a fresh bottle for the best aroma.
- Baking powder: makes the cupcakes rise high and even. Check your can is fresh by testing a little in hot water—it should fizz.
- Salt: balances the sweetness. Choose a high quality kosher or fine-grain salt for best control.
- Sour cream: delivers lots of moisture and tang. Full-fat versions work best in baking.
- Vanilla extract: brings warmth and rounds out the chocolate. Real vanilla extract is ideal for richer flavor.
- Whole or two percent milk: keeps the crumb tender.
- Vegetable oil: adds extra softness and ensures the cakes are never dry. Canola oil is neutral and blends easily.
- Mini chocolate chips: mean even chocolate distribution—use a brand with a bold cocoa flavor if possible
- Powdered sugar: in the frosting ensures a fluffy spread. Sift before adding if lumpy.
- Unsweetened cocoa powder: creates the deep chocolate buttercream color and flavor. Choose a high-quality dutch process cocoa for best results.
- Decorative mini chocolate chip cookies: make these cupcakes especially fun for parties
Step-by-Step Instructions
- Preheat and Prep:
- Line your cupcake pans with paper liners and preheat your oven to three hundred twenty five degrees Fahrenheit so the cupcakes bake evenly from the start.
- Mix the Dry Ingredients:
- In a large mixing bowl whisk together cake flour baking powder cinnamon and salt for about thirty seconds to distribute everything evenly. This ensures that each cupcake is perfectly risen and full of subtle flavor.
- Combine the Wet Ingredients:
- In another bowl stir together sour cream vanilla extract vegetable oil and milk until smooth. This creamy mixture brings the signature moistness and subtle richness to the finished cupcakes.
- Cream Butter and Sugars:
- Beat the softened butter on medium speed until smooth and creamy. Gradually add the white granulated sugar and packed brown sugar and continue beating for about three minutes until the mixture looks pale and fluffy. This aerates the batter for tender cupcakes.
- Add Eggs One by One:
- Blend in the eggs one at a time mixing well after each addition so everything gets fully incorporated and the batter stays velvety.
- Alternate Dry and Wet Mixtures:
- Begin adding the dry mixture and wet mixture to your butter mixture in turns starting and ending with the dry. Use a low mixing speed and scrape the bowl as needed. This slow addition prevents overmixing so the cupcakes bake up soft.
- Fold in Chocolate Chips:
- Gently fold mini chocolate chips into the batter so the chocolate gets spread evenly in every cupcake.
- Fill and Bake:
- Scoop about one quarter cup of batter into each lined cupcake slot. Bake for eighteen to twenty minutes until a toothpick inserted comes out clean or with tiny crumbs. Let the cupcakes cool fully before decorating so the frosting does not melt.
- Make the Chocolate Buttercream:
- Beat softened butter until smooth then blend in vanilla extract. Add powdered sugar salt and sifted cocoa powder. Gradually pour in most of the milk while beating until fluffy. Add a splash more milk if needed until the frosting is creamy and swirly but not runny.
- Decorate:
- Once cupcakes are completely cool pipe swirls of chocolate buttercream on top. Finish with extra mini chocolate chips or a mini cookie for a playful touch.

My favorite ingredient in this recipe is definitely the mini chocolate chips since every single bite feels like a treat. I still remember when my niece learned to pipe her first cupcake swirl using this recipe and she would sneak extra chips from the bowl.
Storage Tips
You can store these cupcakes lightly covered at room temperature for up to two days. For longer keeping refrigerate them in an airtight container for up to five days. Always bring to room temperature before serving for the best flavor. The cupcakes and unfrosted cakes also freeze beautifully—just thaw overnight in the fridge before decorating.
Ingredient Substitutions
No cake flour on hand Use all purpose but remove two tablespoons per cup and replace with cornstarch to make a lighter crumb. Out of sour cream Try full fat Greek yogurt for a similar tang and texture. If you need to make these dairy free use a plant based butter and a creamy non-dairy yogurt instead of the sour cream.
Serving Suggestions
These cupcakes are perfect for birthdays brunches bake sales and class parties. Dress them up with rainbow sprinkles crushed cookies or a drizzle of chocolate syrup. For a fun twist serve with a scoop of vanilla ice cream and chocolate sauce for a cupcake sundae.

Bit of History
Chocolate chip cupcakes bring together two beloved American desserts in one bite. The technique of using both white and brown sugar dates back to vintage home recipes in the early nineteen hundreds when bakers wanted to add softness and flavor. The addition of sour cream started as a way to keep cakes moist for farm gatherings and potlucks before refrigeration was common.
